Biography
Shiyali Ramamrita Ranganathan was born on 12 August 1892 in Sirkazhi, a town in the Madras Presidency of British India. He attended Hindu High School, Matanhail, and then studied at the University of Madras, focusing on mathematics. Initially, he planned to be a mathematician, but his path shifted to library science, a field he significantly changed.
In 1924, Ranganathan became the first University Librarian at the University of Madras, marking a major shift in his career. To gain formal training, he went to University College London to learn library science under leading librarians of that era. When he returned to India, he applied his mathematical skills to library organization and information retrieval. This approach led to his most famous work: the Five Laws of Library Science, published in 1931, which still guide librarians worldwide.
His second key contribution was creating the Colon Classification system, the first faceted classification approach in library science. Unlike earlier systems with fixed categories, Colon Classification used facets to represent different aspects of a subject, allowing more flexible and precise knowledge organization. This idea influenced classification theories in the UK and elsewhere during the 20th century.
Throughout his career, Ranganathan held many academic roles. He was a university librarian and library science professor at Banaras Hindu University from 1945 to 1947, and then at the University of Delhi from 1947 to 1955, where it became the first Indian library school to offer advanced degrees. He was president of the Indian Library Association from 1944 to 1953 and became an honorary member of the International Federation for Information and Documentation in 1957. He was also named a life vice-president of the Library Association of Great Britain.
Recognizing his impact on literature and education, the Government of India honored him with the Padma Shri. He also received the Margaret Mann Citation in 1970 and was inducted into the Library Hall of Fame. Ranganathan continued writing and influencing information science until late in life, working on indexing theory and search methods that anticipated future developments in the field. He passed away on 27 September 1972 in Bengaluru, leaving a legacy that still impacts library and information science worldwide.
Before Fame
Ranganathan grew up in Sirkazhi during the late 1800s and early 1900s, when British rule was affecting educational institutions across India. He showed a strong talent for mathematics early on, which took him to the University of Madras, where he studied and taught mathematics. At that time, he wasn't interested in library science and seemed set on a career in pure mathematics.
Things changed in 1924 when he became the University Librarian at the University of Madras, despite having no library training. Wanting to take the role seriously, he went to England to formally study library methods. This time abroad exposed him to various international library practices and helped him understand what India's libraries needed. His background in mathematics made him prefer systematic and logical frameworks instead of simply adopting Western models, laying the groundwork for his future theoretical work.
Key Achievements
- Formulated the Five Laws of Library Science, foundational principles that continue to guide library practice worldwide
- Developed the Colon Classification system, the first major faceted classification scheme in library science
- Served as the first University Librarian of the University of Madras, establishing professional librarianship as a serious discipline in India

Did You Know?
- 01.Ranganathan's birthday, 12 August, is observed annually as National Librarian Day in India in recognition of his contributions to library science.
- 02.His Colon Classification system, first published in 1933, took its name from the colon punctuation mark used to separate the different facets of a subject heading.
- 03.Despite becoming the defining figure of Indian library science, Ranganathan originally trained and worked as a mathematics lecturer before being appointed University Librarian with no prior library science education.
- 04.He was made vice-president for life of the Library Association of Great Britain, an extraordinary distinction for a non-British national at a time when such institutions were largely centered on Western scholarship.
- 05.His Five Laws of Library Science, first articulated in 1931, are still cited and debated in library and information science literature nearly a century after their publication.
